Executive Summary

The authors presented the simulated BER performance of low-complexity detection of large non-orthogonal STBC MIMO systems in conjunction with a channel estimation scheme. The very good BER and nearness-to-capacity results reported here at practically affordable low complexities point to a key observation that detection and channel estimation need not be a bottleneck in realizing large STBC MIMO systems. Wireless standards (e.g., IEEE 802.11n/VHT, 802.16) can potentially consider such large MIMO systems as options for the future.
